A high-beat mechanical watch depicting the fantastic scenery of an icefall on its dial
This creation exhibits a classic mechanical Grand Seiko case design with a 40mm case size. The dial evokes an icefall that one might encounter in the dead of winter on Mount Iwate, the imposing peak visible from the Grand Seiko Studio Shizukuishi, home to Grand Seiko mechanical watchmaking. Such frozen waterfalls are natural phenomena whereby the water flowing downward gradually solidifies when the temperature drops below freezing. This fantastic scene is depicted on the dial through the dynamic and detailed pattern, as well as a unique icy-blue color.
The case and bracelet are High-intensity titanium, a metal 30 percent lighter than steel and highly resistant to rust, corrosion and scratches.
A dynamic and detailed dial
The city of Hachimantai, in Iwate Prefecture, is the home of Nanataki, a 30-meter waterfall originating from a stream that flows down Mt. Iwate. The dial represents this frozen waterfall, which creates massive icicles during the coldest time of the year. The pattern and color of the di illustrate the dynamism of the frozen Nanataki waterfall and the mysterious expressions found in the bluish-white hue of the ice.
Caliber 9S85
This high-frequency mechanical movement was developed by rethinking the parts that form the foundation of the watch’s precision, granting the level of torque necessary to maintain a high oscillation rate and realizing a practical power reserve of about 55 hours when fully wound.
